Constructed of Polystrand™ continuous fiber reinforced thermoplastic facesheets thermally bonded with a variety of internal core materials including thermoplastic foam and honeycomb core, these engineered composite panels are constructed without secondary adhesives for a stronger bond and more efficient manufacturing process. Uniform high quality High impact strength

Long fiber reinforced composites are renowned for their ability to provide high-impact resistance which enables them to be a solution for a variety of demanding applications. These impact-boosted materials are for use in applications with high cyclical usage and physical demand, especially with drop testing requirements or repetitive impact during use.   Low coefficient of thermal expansion

A higher injection velocity is needed when processing Gravi-Tech due to the thermal conductivity of the material. 2. DETERMINING COOLING TIME Step 1 – Part Cooling Time The first step is to calculate the cooling time of the part itself. 2 • TMelt = Temperature of the molten plastics • TCoolant = Thermolator temperature • TEject = Temperature the parts can eject without deforming • H = Thickness (Use thickest portion of part) • α = Thermal diffusivity Thermal diffusivity can be calculated using the equation below k = Thermal Conductivity Constant • ρ = Density • Cρ = Specific Heat Step 2 – Heat Transfer The next step is to calculate the heat transfer rate.

We’ll help you optimize your product or process leveraging our capabilities with high-filler content compounds, as well as color and additive concentrates, regardless of the demands of your application. Colorant Chromatics™ Conductive Formulations Colorant Chromatics™ Conductive Formulations

The carrier system also has a thermal ceiling and is dependent on both time and temperature. The formulations used to create Omnicolor combine the high tinting strength of organic pigments with the opacity of inorganics.
